See data below from R&T for the M4cs, which's acceleration is close to the G8X. Average acceleration between 50 and 70mph is 0.085mph/s, so the car needs 0.17~0.19s to accelerate from 60mph to 100km/h (62.15mph).
If you can find more detailed acceleration charts for the G8X, we can do the math, but it will be in the same ball park. This is consistent with BMW acceleration quotes, where 0-60mph is usually quoted as ~0.2s faster than the 0-100km/h they post. Slower accelerating cars will be closer to the 0.3s mark.
